THREAD-TRAVERSE MEANS FOR, WINDINGr-MACHINES AND THE LIKE.

material, a traverse railV or other carrier reciprocating substantially parallel with the 1 aXis of the receiving device and a thread guide carried by and reciprocating` with the carrier 'opposite the receivingdevice. For various reasons, depending on the kindv of work being done and similar. conditions, it is inexpedient to `iiX the `thread guide in permanent relation to the carrier, and so it is usually arranged to beadjustable thereon longitudinally of its path of reciprocation, as by securing it thereto yadjustably by screws passed through slots in the thread guide or by springs attached to the carrier and clamping the thread guide thereto. Such expedients Vare known to be very unsatisfactory. The carrier is assumed to have a throw equal to a given length on the receiving device (usually from inside to inside of its f ianges, if it take the form of an ordinary spool, as is usually the case), and the thread guide is supposed to be adjusted on the carrier so that at each limit of its movementy therewith its guiding point will be exactly opposite the corresponding end of said length on the receiving device. This would be entirely satisfactory if in practice it were not the case that the receiving device is frequently not held against but issusceptible of appreciable movement longitudinally of its axis in its bearings, orthat the thread guide is not always properly adjusted on the carrier with reference to ythe receiving device, or that, if it is properly adj usted, it works out of place or becomes displaced accidentally.

The result in actual practice of any failure of the receiving device and the traverse throw of the thread guide to be related properly to each other is inferior product, involving in the case of receiving devices in, the form of spools or other flanged devices Specification of Letters Patent.

a large percentage of waste, because the layrs of windings being shifted out of place one way or the other the wound mass builds up with a channel next to one flange and an elevation next tothe other, and since this elevation when the spool is completely filled has no flange-support it readily slips endwise off the wound package in handling and the thread it represents must be discarded.

, In place of arranging the thread guide on the carrier in fixed, though adjustable, relation thereto I mount it thereon so as to be freely movable longitudinally of its reciprocating path and provide means to limit in each direction its movement with the carrier. Ifthe rotary receiving deviceis perchance suitably held against appreciable movement longitudinally of its aXis, as in certain instances may be the case, said means is arranged immovably on the Vframe or other support. If it is not so held, then said means is confined by said device against movement relatively thereto longitudinally of its aXis, as by bearing against the ends thereof.

I have shown in the accompanying drawings both of the above statedA forms of my invention, each of which may be constructed in various other ways than as shown without departing from the spirit of the invention,

Figures l and 2 being a side elevation, partly in section, and a `plan of the first form;

Fig. 3 a plan of the second form; and

Figs. 4 and 5 a front elevation and a transverse section of the thread guide and carrier.

Referring, first, to Figs. l and 2: a is a suitable support including brackets in which to support the receiving device and brackets c in which the thread guide carrier reciprocates. Z is the receiving device, having a iiange d at cach end and being therefore in the present instance an ordinary spool; its axial spindle e is journaled in the brackets 7), and carries a driving whirl The spool may be driven from a drive-wheel g, on a shaft 7L journaled in the frame, by contact of its whirl. therewith. z' is a bar,

varranged in brackets c, over which the thread extends to the spool from its source of supply (not shown). j is the traverse rail or thread guide carrier arranged to be reciprocated by suitable means (not shown) in the brackets c. T he spool and traverse rail are arranged horizontaily, the elements so Vio fio

cnes 9i this patent' may be obtained for far described being those ofV a well-known type of horizontal Windingl machine. The spool in this instance is supposed to be held against any appreciable movement longitu-` dinally Aof its axis (see Fig. 2).

7a is the thread guide, the same having a guiding notch 7c and, on each side thereof, the impact face 70". It is freely slidable on the traverse rail, being in thel present instance retained on the same by the front and rear cheek pieces [attached to the traverse rail. l y

rIhe means to limit iii each direction the movement of the thread guide with the traverserail is Yin the present instanceva'foilishaped piece m 'which is attached to the frame so that its ends project over the traverse rail. The plane of the inner face m of each such end is vdistanced from the plane of the inner faceV of the adjoining spool flange the same as the verticalv planes in which lie the guidirI g notch 7c Vand either impactk face 79 of the thread guide.

' rlhe pressure of the thread being Wound on the thread guide keeps up sufficient friction between the latter and the traverse rail so that the thread guide tends to remain in one place Y on the traverse rail. Since the effective distance between the faces 'm' of the means m is equal'tc'the actual distance'between the inner faces of the spool flanges the guiding point, (notch ls) of the thread guide is made on movement of the latter in each direction to come in direct alinement With vthe inner face vof the corresponding spool flange; for, if, asfby shifting of the thread guide on'tlie rail from any cause, it would otherwise be carried so fai' in either direction that its 'guiding pointwould pass the inner face of the spool flange, the thread guide Will be checked With its guiding point registering with the inner face of said flange by contact' with the adjoining face m of the means fm, sliding on the rail till the latter completes its movement. Thus throughout the Winding the layers are made to terminate all in the same plane at each end of the mass'of windings. i

Referring to Fig. 3 Here the parts are all the same as described above excepting the means to 'limit in each direction the movement of the thread guide, and excepting, also, that the receiving device is susceptible, as shown, of longitudinal movement in its bearings. in this case the ieccivinO device n. 7 D

means, being a forli-shaped piece as before, is slidable ina holder 0 attached to the frame, its ends bearing against the ends of the receiving device, which it hugs rather closel 7; he piece a is kept horizontal by a pin-and-slot'connection p with itsv holder o. Here, again, the plane of the inner face nf ofeach end of the piece n is distanced from the plane of the inner face of theadjoining spool'iia-nge the same as the'vertical planes in which lie the guiding-notch 71: and either impact face 7c of the thread guide.

rIihe resultof this arrangementV is obvi- V.ousl f the same as that rst described the means to limit the movement ofthe 'thread guide being here confined against movement relatively to the receiving device longitudinally of its axis directly by said device instead of both being confined against such inov'ementfby the supporting structure.

Having thus fully described'my invention,

vwhat l claim and desire to secure by Letters Patent is: l

1. Means for Winding thread With a trav= erse including, with a support, a rotary receiving device on which to Wind the thread,

a thread guide carrier reciprocating substantially parallel with the axis of thereceiving device, a thread guide carried by and normallyreciprocating With the carrier opposite the-receiving device andfree t0 move on the carrier longitudinally of its reciprocating path, f andmeans to stop in each direction the reciprocating in ven`ient of the guide with the carrier.
